Title: Hydraulic vibrator for swarf removal from machined parts - has stepped piston with fixed and variable orifices
Inventor: KOSCHELEW NIKOLAI WASILIEWITSC
IPC: B65G27/22
Filed: 1974-03-14
Abstract: The piston (7) has a large diameter section (8) and a small diameter section (9). Hydraulic fluid is supplied under pressure to the inlet (6) into the space (10) and then flows through the hole (19) into the hole (22) through the right-hand orifice (23) into the space (17). Because of the pressure drop through the orifice (23) the piston moves to the right until the orifice (32) is closed by the valve head (33). The consequent rise in pressure in the space (17) pushes the plunger (13) to the left so that the high pressure fluid in the space (10) flows to space (12) pushing the piston (7) to the left until the orifice (31) is closed and the cycle is repeated.

Title: Superheterodyne receiver with oscillator - is automatically reset to correct frequency if it deviates from nominal value for channel
Inventor: KLANK OTTO ING GRAD
IPC: H03J7/02
Filed: 1974-08-31
Abstract: The oscillator is reset by a control voltage which is generated by the mistuning, and there is a counter (11) which is used to count the number of the oscillator oscillations. The frequency steps which are counted by the counter are shorter than the frequency steps between the nominal frequencis, to which fixed counter readings are allocated, and the control voltage is derived from the counter (11). The size of the step changes in frequency is reduced as the actual frequency of the oscillator approaches the nominal frequency. A gate (10) is used and is connected to the counter (11) and to the manual control (E) for setting the desired frequency.

Title: Timing switch for daily differing operating periods programming - uses slider potentiometers for each day and a common clockwork potentiometer
Inventor: CHOWANECZ HANS B DIPL ING
IPC: G05B19/07
Filed: 1975-04-10
Abstract: The timing switch is intended for programming a daily varying operating time period for electric apparatus and systems. The daily varying program is preset for each instance on a slider potentiometer for the ON or OFF switching for each day. This arrangement cooperated with a rotary potentiometer, driven by a timing switch, in such manner that its continuously reduced resistance is brought into relation with the slider potentiometer system. All the potentiometers have preferably identical rated resistances. In the OFF condition the resistance of rotary potentiometer is added to the ON slider potentiometer of the respective day. If the total resistance of the two potentiometers is below the rated resistance of the two potentiometers, a flip-flop amplifier switches on the electric apparatus.

Title: Vessel closing system used for covered dishes - heats upper portion of vessel in order to create vacuum before welding lid into place and sealing
IPC: B65B7/28
Filed: 1975-05-14
Abstract: The vessel closing system welds a lid to it after filling with food. To generate a vacuum the upper portion of the vessel is heated, and the lid is then welded into place. Before the welding operation, the upper portion of the vessel, together with the lid placed on it, can be heated, (6) or the lid can first be partly welded in place, after which heating and then final welding are carried out. The process avoids the lid bellying outwards, and reduces the air inside the vessel to the minimum, thus assisting in preserving the contents.

Title: Reciprocating electromagnetic drive for impact tools - has hollow armature containing freely movable mass
Inventor: SCHAEFER PIETER
IPC: H02K33/02
Filed: 1975-06-25
Abstract: An electromagnetic device is for hammers or similar impact tools. The solenoid winding (14) contains an armature (18) which is located by bearings (26, 28) at either end in which it can more axially when the winding is excited. The armature is hollow and contains a mass (34) which is free to move axially independently of the armature. When exicted for a working stroke the light armature accelerates rapidly to full speed before striking the mass (34) with the internal boss (38). The mass then travels through the armature bore and strokes the boss (36) at the opposite end thus giving an extra impact to the stroke. Return of the armature assembly to the starting position is by a slow stroke. In a typical tool the solenoid acts through a hydraulic linkage (42, 44, 46) on the working piston (48) attached to the tool head.
